In the second semester of his sophomore year in high school, Lin Zhi transferred to another school and met his classmate Chen Jin, who lived alone. Two people who are used to living alone gradually get closer from observing each other. Cheng Yan's troubles made Lin Zhi see his true feelings clearly. During spring outings, taking care of sick people, feeding cats, and preparing for exams, the two of them went from being at the same table to becoming the most trusting people in each other within a year. On the day after the college entrance examination, Chen Jin was waiting for her outside the examination room with the pork rib soup he had stewed. The story stops at the words "The days are long".
